(2)Transmission speed:
2400,4800,9600,19200 BPS (selectable)
(3)Synchronization:
start-stop synchronization
(4)Transmission parameter
■
Parity:
None, EVEN
■
Start bit:
1-bit
■
Stop bit:
1-bit
■
Word length
8-bit
(5)Error detection
■
Parity check: VRC (Vartical parity check)
■
Framing error: This error occurs when no stop bit is found in the frame specified startig
with the start bit.
■
Overrun error: This error occurs when subsequent data is input before the data input to
the UART from the host is read by the printer.
(6)Data entry code: ASCII, 8-bit code for European characters, 8-bit code for graphic
(7)Receiving buffer: 5 KB
(8)Protcol
■
XON/XOFF (DC1/DC3) protocol
•
When initialized after power on, this printer becomes ready to receive data and sends
an XON code (11H). (Trasmission or non-transmission of XON code is selectable by
means of the DIP switch.)
•
The printer sends an XOFF code (13H) when the blank positions in the receive buffer
becomes 800 Bytes or less.
•
The printer sends an XON code (11H) when the blank positions in the receive buffer
are 2KB or more.
•
When there are no blank positions in the receive buffer, the printer discards data
received which exceeds the receive buffer capacity, without storing it in the buffer.
(After detecting the XOFF code, the host computer must stop transmission before the
printer receive buffer becomes full.)
•
The ptinter sends an XOFF code (13H) at power off time. (XOFF code send is selectable with
Dip switch.)
